GAUGE AND COO PERATING CUTTER.

Application filed May 27, 1927, Serial No. 194,716. Renewed luly 1,1929.

The present invention relates to gauges and (Jo-operating cutters forapplication to a sewing machine, or other suitable piece of mechanism,and has for an object the more rapid and perfect control of the materialto be cut.

It is also an object of my invention to provide a gauge and co-operatingcutter for quick and convenient application to a sewing machine, andparticularly to that class of sewing machines adapted to the hatindustry.

With these and other objects in View, which will become apparent as thedescription proceeds, my invention consists of the novel parts andcombinations of parts, all as hereinafter will be more fully describedandparticularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews.

Figure 1 is a side view of a small sewing machine equipped with my gaugeand co-operating cutter.

Figure 2 is an enlarged view of my gauge dis-assembled.

Figure 3 is an end view of this sewing machine equipped with my gaugeand co operating cutter.

Figure 1 is a plan view of the feed mechanism of the sewing machinewhich is slotted to allow space for the cutter.

Figure 5 is the cutter support, cutter, and small auxiliary gauge, and

Figure 6 is one of my cutter supports, cutter, and auxiliary gaugedis-assembled.

In the drawin s 10 is my gauge bracket adapted for attac ment to thecasting of the bed-plate of the sewing machine 11 by means of the screw12 and the dowel pin 13. The boss member 14 is drilled throughvertically to provide a hinged bearing for the member 15 which swingsabout the large dowel pin 16 and the said member 15 is further equippedwith a stationary dowel pin 17 adapted to enter a hole in the bossmember 14 and to hold the member 15 firmly in closed position againstthe base member of the sewing machine, except when the member is lifted,freeing the dowel pin 17 from its hole and seat, when the said member 15is free to swing outward about the large dowel pin 16 as a center. Themember 15 is further equip 366. with the slot-way 18 adapted to receivet e shank of the screw 19 which enters the threaded hole 20 in the gaugesupport 21, and the said gauge support 21 enters the channel guideway 22in the member 15 with a neat sliding fit, thereby providing thehorizontal adjustment of my gauge, which comprises the large flattenedand flaring member 23, and the smaller associate swing member 2ladaptedfor attachment to the member 23 by means of the screw hole 25, the screw26 and'the threaded screw hole 27 It will now be readily appreciated howI may swing my gauge outward by lifting it, how I may secure horizontaladjustment by loosening and sliding the thumb screw 19 which moves themember 21, and how I may loosen the screw 26, and swing the gauge member24 over the gauge member 23, and how I may control the position of ahat, for example shown at 28 in dotted lines. The cutter 30 is shownsecurely clamped in the cutter carrier 31 by means of the set screw 32which cutter carrier 31 isattached to the foot bar 33 of the sewingmachine. The cutter carrier 31 is further provided a with the smallauxiliary gauge member 34 attached by means of the screw 35 and washer36.

In operation, in cutting the brim of a felt hat for example, I adjustthe. gauge to con trol the desired depth of insertion into the machineand under the cutter of the felt brim, the brim is inserted, the gaugeswung into closed and locking position, the footbar carrying the cutteris lowered, and the felt of the hat is pressed against the feeddog ofthe sewing machine which imparts the motion to the felt of the hatagainst the cutter blade. I secure rapid and flexible adjustment, and asharp clean cut of the fabric under the knife. In some operations theremay be several thicknesses of material for example, and under certainconditions it is necessary or desirable to bring into play the smallauxiliary gauge34= to co-operate with the main gauge members 23 and 24.Whereas I have shown and described a swing adjustable gauge andco-operating cutter, with auxiliary gauge of a definite design, I may ofcourse alter the shapes or forms of the gauge, cutter, and auxiliarygauge, without departing from the spirit of the invention or alteringits mode of operation, or the mutually co-operating action of the gaugeand cutter, or of the gauge, cutter and auxiliary gauge, and whereas Ihave shown my attaehments upon a small sewing machine machines, or

for the hat industry, I may of course apply my devices to general andsetting up sewing to any other kind of machine adapted to feed fabricunder the cutter of its carrier.

Having described my invention, I claim 2- l. A work gauge forapplication to a sewing machine, comprising a bracket With a hingemember, a bar member adapted to swing on the hinge member, the said barmember carrying a gauge member horizontally adjustable, and a secondgauge member pivoted on the first gauge member to provide a spacetherebetween for said work.

2. A gauge for application to a sewing machine, comprising a bracketwith a hinge member, a bar member adapted to swing on the hinge member,a dowel pin rigid with the bar member and in association with the hingemember adapted to hold the bar member in a fixed position, a gaugemember latorally adjustable in the bar member, and a second gauge memberpivoted on the first gauge member in spaced relation thereto.

3; Awork gauge for application to a sewing machine, comprising a bracketmember with a hinge member, a bar member adapted to swing on the hingemember, the said bar member provided with a channel-way and a slot-way,adapted to receive adjustably the shank portion of a gauge member, athumb screw adaptedto clamp the said shank portion immovably in thechannel-way of the said bar member, a major gauge member carried by thesaid shank portion, and a minor gauge member adjustably secured theretoto provide a space therebetween for reception of the work.
